BAND-CUTTER AND FEEDER FOR THRASHIN G-MACHINES'.

SPECIFICATION forming part of Letters Patent No 347,280, dated August10, 1886.

Application filed November 6, 1885. Serial No. 1:2;031: (No model.)

.To all whom it may concern.-

Be it known that I, JACOB W. TURNER, of Middle Point, in the county ofVan \Vert and State of Ohio, have invented a new and usefulImprovementin Band-Cutters and Feedersfor Thrashing-lvlachines, of whichthe following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan view of one of my improved machines, part beingbroken away. Fig. 2 is a longitudinal vertical section of the same,taken on the broken line or mom, Fig. 1. Fig. 3 is a front end elevationof the same, partly in section. Fig. 4 is a transverse vertical sectionof the same, taken through the line y y, Fig. 1.

The object of this invention is to improve the construction of theband-cutters and feeders for thrashing-machines for which Letters PatentNo. 319,940 were issued J nne 9, 1885, to J. \V. Turner and E. V.Strack, in such a manner as to make them more convenient in use and morereliable in operation.

The invention consists in the construction and combination of variousparts of the machine, as will be hereinafter fully described.

A represents the frame of the machine. To

the rear ends of the side bars of the frame A are attached bars B, forconnecting the machine with a thrasher. To the forward parts of the sidebars of the frame A are attached keepers O, to receive the upper ends oflegs D, for supporting the forwardend of the machine. To the side barsof the frame A is attached a close bottom, E, to support the upper partof the endless apron F in a horizontal position while carrying the grainto a thrashing-cylinder.

The endless apron F passes around rollers G, journaled to the endpartsof the side bars of the frame A, and to the said endless apron areattached at suitable distances apart crossbars H, which are providedwith teeth I, to engage with the grain and carry it to the cylinder.

Above the rear roller G is placed a feedroller, J, to feed the grainregularly to the thrashing-cylinder and prevent it from being drawn intothe said thrasher too fast, and be ing thus liable to choke thethrasher. The feed-roller J is provided with annular grooves K, to allowthe teeth I of the cross-bars H to pass without coming in contact withthe said roller. The feed-roller J isjournaled in bearings in slottedstandards L, attached to the rear ends of the side bars of the frame A,and is held down by spiral springs M, or other suitable springs,interposed between the said bearings and the caps of the said standards,so that the said roller can adjust itself to the quantity of grain beingcarried forward.

To the forward ends of the side bars of the frame A are attached keepersN, in which rests the lower edge of the end board, 0, which is furthersecured in place by buttons P, )ivoted to the edges of the inclinedfeed-tables Q, so that the said end board can be readily detached whenrequired.

The upper edges of the forward parts of the side bars of the frame A arerecessed to receive the inclined feed-tables Q, which are connected withthe said side bars by hinges It. The feed-tables Q are supported inplace when in use by brace-hooks S, the upper ends of which are hingedto the outer parts of the said tables by eyescrews T or other suitablemeans. The lower ends of the bracehooks S are hooked into the eyes ofeye-plates U, attached to the lower parts of the side bars of the frameA; so that the said brace-hooks can be readily unhooked to allow thefeed-tables Q to be turned down when not required for use.

The upper and lower edges of the end board O,at their centers arerecessed to receive metal straps V, attached to the upper and loweredges of the forward end of the divisionboard W', to holdthe saidforward end from lateral or vertical movement. The rear end of thedivision-board \V is secured to a cross-bar of the frame A. The upperedge of the division board W, near its inner end, is recessed to receivethe two pairs of truncated conical rolls X, placed upon the shaft Y,uponthe opposite sides of the'cutters Z, attached to the said shaft Y. Theconical rolls X are arranged with their smaller ends next the cutters Z,so that-the said rolls will tend to move the bundles of grain passingbeneath them toward the cutters Z, and thus insure the cutting of thebands. The cutters Z are made with teeth curved upon one edge andstraight upon the other, as shown in Fig. 2, and sharpened upon bothedges, so that the said cutters can be rotated in either direction, asmay be desired, and will cut off any grainstalks that may tend to windabout them. The shaft Yrevolvesin bearings attached to the upper edgesof the side bars of the frame A.

In bearings 0, attached to the upper crossbars of the frame A,arejournaled the arms of cranks b, to which are hinged the frames 0. To thebottom bars of the framescare attached teeth (1, to engage with thebundles of grain after their bands have been cut, and spread the stalksevenly over the endless feed-apron F. To the rakeframes 0, below thecranks I), are hinged the ends of a connecting-rod, c, to hold the saidrake-frames cparallel with each other and cause them to move together.One of the rake-frames c is extended above its crank I), and to its topbar is hinged the end ofa COllllCClllllgdOtl, f, the other end of whichis pivoted to the crank-pin ofa crank or crank wheel, 7, attached to theend of a short shaft, 71. The shaft 71 is jonrnaled in a long bearing,i, attached to the edge of a side bar of the frame A, and to its otherend is attached a beveled gearwheel, j, the teeth of which mesh into theteeth of the beveled gear-wheel 7.x, attached to the shaft Z. The shaftZ revolves in bearings attached to the frame A, and to it are attachedbeveled geanwheels m, the teeth ofwhich mesh into the teeth of thebeveled gear-wheels 01, attached to the cranks b, so that the rakes willhave at the sametime an oscillating movement and an up-and-downmovement, and will thus spread the grain evenly over the endless apron;To the bottom bar of the extended rake-frame c is attached the end of aspring, 7,which projeets into such a position that its free end willcome in contact with the connecting-rods c f at each end ofthelateralmovement of the rakeframes, and will thus relieve the said rakeframesfrom the jar as the direction of their lateral movements is reversed.

To the upper edges of the side bars of the frame A are attachedhearings, in which revolves a shaft,o, to one end of which is attached apulley, p, to receive a belt from the driving mechanism of the thrasher.To the other end of the shaft 0 is attached a cone-pulley, q, aroundwhich passes a belt, 1'. The belt ralso passes around a cone-pulley, 8,attached to a journal of the forward roller G, that carries the endlessfeed-apron F, so that by shifting the said belt 1' the said endlessfeed-apron can be driven at a greater or less speed, as the condition ofthe grain may require. To the journal of the roller G is also attached apulley, 15, around which passes a belt, a. The belt it also passesaround a pulley, 1;, attached to the end ofa shaft, w, journaled to theside bars of the frame A. To the end of the shaft 10 is also attached apulley, as, around which passes a belt, 1 The belt yalso passes around apulley, 2, attached to the end of the shaft 1, so that the rakes will beoperated from the shaft 0. To the other end of the shaft 1/; isattacheda pulley, 1, around which passes a belt, 2. The belt 2 is crossed andpasses around a pulley, 3, attached to a journal of the feedroller J, sothat the said feed-roller will be driven from the said shaft a. To theother journal of the rear roller G, that carries the endless feed-apronF, is attached a pulley, 4, around which passes a belt, 5. The belt 5also passes around a pulley, 6, attached to the end of the shaft Y, thatcarries the cutters Z and the conical washers X, so that the saidcutters will be driven from the said roller.

The belt 5 may be straight or crossed, ac cording as it maybe desired torun the cutters Z in one or the other direction.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a band-cutter and feeder forthrashing-machines, the combination, with the frame A, the shaft Z andits driving mechanism, the rake-frames c, and the beveled gear-wheelsjk, the crank y, and connecting-rods f e, for vibrating the saidrake-frames, of the beveled gear-wheels ma and the cranks b,substantially as herein shown and described,whereby the said rake-frameswill receive a lateral movement and an up-and-down movement at the sametime, as set forth.

2. The combination, with therake-frames c, the crank-shafts b, on whichsaid frames are mounted, means for operating said crankshafts, and therod 0, connecting the lower bars of said frames, ofthe crank-wheel therodf, connecting the said wheel to the top of one rake-frame, and thespring 7 on the lower rail of one frame,extending in alignment with andbetween said connecting'rods, whereby when the frames are operated thespring will alternately strike the connecting-rods,substantially as andfor the purpose set forth.
